The problem is clear if you understand the basic principles at work here: at a gay wedding, you have a whole lot of wangs pointing in the same direction, like a bunch of psychic daggers - it's the same principle that says you don't want shelves of books in uncovered bookcases. With as much bad feng shui as a gay wedding would bring, the owner might as well have just built his restaurant on the back of a drag... queen. This isn't rocket science.

Also, there's a long-standing rivalry between Chinese feng shui masters and Western interior designers that is almost certainly at the heart of this.
